G'AS-GENERATOR4 FOR INTERNAL-COMBUSTION ENGINES.

Application filed February 11,1914. Serial Nol 817,965.

To all whom it may concern: f

Be it known that we, CARL C. Rio'r'rn, deceased, late a citizen of the United States and resident of Jersey City, Hudson county, New Jersey, and BENJAMIN C. SMITH, a citizen of the United States, and residing t at Bayonne, Hudson county, New Jersey,

have invented certain new and useful Improvements in Gras-Generators for Internal- Combustion Engines and the like, of which the following is a full', clear, and exact description.

This invention relates to an 'improved means for forming and delivering gas to internal combustionengines, the object of the invention being to provide an improved cori struction whereby the heavier liquid hydrot carbon fuels may be successfully used therein. y Y

Heretofore great dilicultyhas been experienced' in the attempts that have been made to use the .heavier liquid hydrocarbons in this connection because it has been Iimpossible to prevent some vof the fuel in liquid form from reaching the interior of the engine cylinder. When any of the fuel in solid form is ldrawn into the cylinder, it burns imperfectly and results in the rapid accumulation of carbon on the cylinder walls and piston head to the injury of the efficient operation of the motor. y By the present improvement, means is provided for effectively overcoming the difficulties heretofore standing in the way of complete success in the use of such fuel.

In the drawings, Figure 1 is an end elevation', partly in section, of a part of an engine equipped with this improvement. Fig. 2 is a relatively enlarged detail view shown in perspective and in section on the linev 2-2, Fig. l. Fig. 3 is a cross section on the line 3 3, Fig. l. Fig. 4 is a crosssection on the line 4 4, Fig.` l.

l represents conventionally a motor of the internal combustion engine variety.

2 represents the exhaust port.

3 represents the exhaust pipe.

l represents' conventionally a feed tank designed'to hold liquid fuel at the proper level relatively to the sprayer tips 5. These tips are located in an air passage through which air may rush with a sufficient velocity to draw off, in the form of spray, the proper proportion of liquid fuel to -mix with the air.

6 is a pipe leading from -the sprayer tips 5 upwardly to a pipe 7, which represents the gas intake pipe of the motor, the same leading to the usual valved intake Port (not shown.) The pipe preferably leads through the exhaust pipe 3 so that the hot exhaust gases will constantly maintain the pipe 6 at a high temperature, while the engine is running. v v

8 is a jacket which may surroundthe pipe 7 to prevent toorapid radiation of heat so that gas passing through the pipe 7 on its way to the cylinder head will not condense. In the ,Zone where the pipe 6 connects with the piper7 is provided a separator means which is shown in detail in Fig. 1 in the vimmediate vicinity of the section line 4-4 through to partake of atortuous or circuitouscourse, said means in one form compris- I Specification of Letters Patent.

ing the baffle members 9-9. The pipe 6 may be of rectangular cross section, as shown 4in Fig. 8. It will be seen that a mixture of air and atomized fuel flowing 'in the course indicated by the arrows through the pipe 6 `will be constantly deflected in Aa direction to tend to throw anysolid particles of fuel either against the side wallsof the pipe 6 or against the deflectors v9 where said solid particles of liquid fuel will lodge'and, under the direct heat thereof, be transformed into gas. Inasmuch as there may be some solid 4fuel passing, through the pipe 6, and inasmuch as it is necessary to prevent any of the solid fuel from entering the cylinder, there is provided in combination with `the pipe 6 and cooperating therewith the is to remove from the gas mixture any solid preferred form comprises the spiral ar-' ranged in the pipe extension at the end of 2 the pipe 6 formed by a plate twisted about its longitudinal center line with its edges engaging the interior of pipe 7 as shown in Figs. l and 4, which will impart to the gases a rotary movement as they pass or progress therethrough. |llhis pipe extension has, adjacent to the spiral 10, one or more outlets, preferably in the form of longitudinal slits ll-11, which preferably enter the pipe tangentially, asbest seen in Fig. 4, so that the action will be as follows: When the gas mixture-has passed from the pipe 6 into the separator, it is given a rapid spiral or circuitous movement which tends, by centrifuf'gal action, to throw such solid fuel out against the side Wall of the separator, Where it is forced through one or the other of the outlets ll into the space between the outside of the separator and the jacket pipe 8, si)r that the gas mixture beyond the separator will be free from solid liquid fuel, hence the gas delivered to the engine is bound to burn freely andl completely and without injuriously sootihg the inner Walls of the cylinder or piston head.

lf desired, a drain pipe 12 may be provided leading from thev space around the i sepa-rator to the source of fuel supply or to any discharge point, so` that any unmixed liquid fuel discharged from the separator need not necessarily be wasted..

Obviously any suitable means may be employed to heat the pipe 6, but for economys sake, it is preferred to use the hot exhaust gases of the engine.

Obviouslyl since any fuel may be used in the apparatus, if it is desired to start the en-l gine with gasolene for the purpose of first heating up thev parts preparatory to turning on thefeed of heavier hydrocarbons such as kerosene, this method may be adopted, but no invention is claimed in this methodpf starting.

While the invention is shown in its preferred form, it is' apparent thatmodiications may be made inthe construction and design. l

`It will be observed that the Jjacket pipe 8 performs the second function of Lclosing the pipe 7 to the admission of air at a point beyond the pipe 6, for it issobvious that air should not be permitted to leak through the slits 1l to adulterate injuriously the gas mixture, it being ,preferred to adjust the proportions of the mixtureat the atomizing end. Any form of adjusting means may be provided for this purpose. 4In the drawings 14 represents a valve of conventional form designed to control the.fuel supply delivered at the tips 5 5.
